GN5 / Add sign in/out support

Currently, when deploying GeoNetwork 5 with GeoNetwork 4 sign in operation are managed by version 5. This adds the possibility to sign in from GeoNetwork 4 directly.

Configuration steps for GN4 are:

* start with `-Dgeonetwork.security.type=gn5`
* In `config-security.properties`, configure the URLs for login and logout to point to GN5 (this could maybe be avoided with X-Forwarded headers?):

```properties
logout.success.url=http://localhost:7979/geonetwork/srv/eng/catalog.search
loginForm=http://localhost:7979/geonetwork/srv/eng/catalog.signin
loginErrorForm=http://localhost:7979/geonetwork/srv/eng/catalog.signin?failure=true
```

* In UI configuration, enable the authentication and set the signin/signout URLs to use the GN5 URLs:

```json
     "authentication": {
          "enabled": true,
          "signinUrl": "../../{{node}}/{{lang}}/catalog.signin",
          "signinAPI": "../../api/user/signin",
          "signoutUrl": "../../api/user/signout"
```
